（2）頻度副詞在句中的位置

1）表示不確切頻率的副詞通常是用在句中的。而其在句中的確切位置，還與句中的動(dòng)詞形式有關(guān)。具體來說有以下幾種情況：

①用在實(shí)義動(dòng)詞之前，be（am，is，are，was，were）動(dòng)詞和助動(dòng)詞（will，should，have）之后。

a. I often do some shopping on weekends.

b. She is often late for school.

c. I have never seen him since we parted.　自從分別后我就再?zèng)]見過他。

②若句中的謂語動(dòng)詞由多個(gè)部分組成，比如：will be done，should have done等，這時(shí)副詞一般要放在第一個(gè)助動(dòng)詞之后。例如：

a. This project will never be finished.

b. You should never have trusted him.　你永遠(yuǎn)都不應(yīng)該相信他。

③在加強(qiáng)語氣的句子中，我們一般是把副詞放在第一個(gè)助動(dòng)詞之前或be動(dòng)詞之前。例如：

a. You really will get a reward one day.　總有一天你會(huì)遭到報(bào)應(yīng)的。

b. —As a teacher, you should always be patient with students.

—I always have been patient.

④在只有助動(dòng)詞而省去了實(shí)義動(dòng)詞的句子中，副詞一定要放在這個(gè)助動(dòng)詞之前。例如：

a. —You should have known better than to trust him.

你早就應(yīng)該知道他這個(gè)人靠不住。

—I never will.?。ㄊ∪チ藅rust him）我今后再也不會(huì)相信他了。

b. —Can you find a place to park your car in the street?

—Yes, I usually can.

c. Plenty of teenagers with computer skills are skipping school, or at least deferring for a few years. But while some kids have found decent incomes without college, most never will.

很多具有電腦技術(shù)的青少年輟學(xué)或休學(xué)了，盡管有些孩子離開學(xué)校后找到了收入不菲的工作，但大多數(shù)永遠(yuǎn)不會(huì)。

副詞也要用在省略了表語的be動(dòng)詞之前。

—I hear that his American girlfriend used to be his English teacher.　我聽說他的美國女友曾是他的英語老師。

—No, she never was.　不，她從來不曾是。

2）表示確切頻率的副詞一般只能用于句末。例如：

a. Milk is delivered daily.　牛奶每天都送來。

不說：Milk is daily delivered.*

b. We have meetings twice a week.

比較：We often have meetings.

c. They will be paid yearly.

3）上述表示不確切頻率的副詞，有些也可以用于句首或句末。例如：

Often/Sometimes/Usually I work late into the night.

我常常/有時(shí)/通常工作到深夜。

often一般不單獨(dú)放在句末，而須加very或quite修飾。例如：

a. He comes late for school quite often.

b. Often he comes late for school.

c. He often comes late for school.

4）always可在句末，但不能放在句首，除非用在祈使句中。例如：

a. You always make the same mistakes.

b. You make the same mistakes always.

不說：Always you make the same mistakes.*

但在祈使句中，我們說：

Always remember not to argue with your boss.

5）在否定句中的頻度副詞

在否定句中，有的頻度副詞位于not之前，有的頻度副詞位于not之后。這主要是從意思上來判斷。一般來說，always要放在not之后（not always）；而often，sometimes，usually要放在not之前。例如：

a. He doesn't always leave before 6 o'clock, sometimes he works until 8 o'clock. （不總是）

b. His wife complains that he sometimes doesn't listen to her.　（有時(shí)不）

c. The history lectures sometimes aren't interesting.

歷史課有時(shí)很沒勁。

不說：...he doesn't sometimes listen to her.*

...aren't sometimes interesting.*

6）否定頻度副詞never，rarely，seldom有兩點(diǎn)須注意：

①不能再與否定詞not連用。例如：

不說：He doesn't seldom go out at night.*

應(yīng)說：He seldom goes out at night. 他晚上很少出門。

②一般只用在句中。若放在句首，則句子要用部分倒裝。例如：

a. I have never heard such a story.　我從來沒聽說過這樣的故事。

b. Never have I heard such a story.

總的來說，對(duì)于頻度副詞在句中所使用的位置，我們應(yīng)注意以下幾點(diǎn)：

1.表示不確切頻率的副詞通常用在句中，其在句中的具體位置又與句子的謂語動(dòng)詞形式有關(guān)。

2.表示確切頻率的副詞一般只用在句末。

3.要注意否定詞與頻度副詞連用的位置關(guān)系。
